Both the Pope and I oppose the death penalty, period. I was baptized a United Methodist in 1981 and my church then opposed the death penalty in its social principles.
Pope Francis changes church's teaching on the death penalty
At that 2017 ceremony, Francis said the death penalty violates the Gospel and amounts to the voluntary killing of a human life, which "is always sacred in the eyes of the creator."
Besides for Christian reasons, I feel that the criminal justice system is sometimes flawed, even with the best intentions, and wrongly convicts the innocent to die by the state. Being confined for life should be the maximum punishment for the most heinous of offenses.
In the following, people were about to stone a woman caught in the act of adultery -ACCORDING TO BIBLICAL LAW given under the old covenant. More correctly, according to JUDGMENTS UNDER THE LAW. THE LAW being the ten commandments which were WRITTEN IN STONE. JUDGMENTS, however, are, as it were, WRITTEN IN SAND -and change according to what is necessary for the present phase of God's overall plan. The old covenant prepared a people for the new covenant -and it was time for judgments to change in order to further prepare a people to become children of God and citizens of the kingdom of God -who will "not hurt or destroy".
John 8:3And the scribes and Pharisees brought unto him a woman taken in adultery; and when they had set her in the midst,
4They say unto him, Master, this woman was taken in adultery, in the very act.
5Now Moses in the law commanded us, that such should be stoned: but what sayest thou?
6This they said, tempting him, that they might have to accuse him. But
Jesus stooped down, and with his finger wrote on the ground, as though he heard them not. 7So when they continued asking him, he lifted up himself, and said unto them,
He that is without sin among you, let him first cast a stone at her. 8And again he stooped down, and wrote on the ground. 9And they which heard
it, being convicted by
their own conscience, went out one by one, beginning at the eldest,
even unto the last: and Jesus was left alone, and the woman standing in the midst.
10When Jesus had lifted up himself, and saw none but the woman, he said unto her, Woman, where are those thine accusers? hath no man condemned thee?
11She said, No man, Lord. And Jesus said unto her,
Neither do I condemn thee: go, and sin no more.
Under the old covenant, sin was removed from Israel by literally removing sinners by death at times -while the necessary mindset was taking root in them.
They had limited power and ability to remove sin from themselves in letter or spirit.
The new covenant focuses more on removing sin from the sinners themselves -and God making available his spirit to many (a spirit of "power, love and of a sound mind) makes possible removing sin from the sinner more so in letter and also in spirit.
If a government -or any part thereof -seeks to align with Christ's teachings, they will likewise not condemn or put to death -but they are still responsible for making decisions to protect the innocent and vulnerable.
